4inoveanent trein the device to a onto the siding,jor other track,

eThis invention relates to improvements in t; operated railway switchesand .dc-'signed for automatically a moving train from one 'track toy'ithout marinai assistance.

the invention consists in locating 'een the ral outside et the saine, ad rice which is adapted to he streelt hya or projection carded on thetrain. rihe .n nent ci this part 'transmits a memher which is located soto he held down hy the tread portion oi? the wheel during the passage eithe train into the switch. The moveme oi the device and member throw theswitch eo as to permit the train naive mld the switch .in this openposition nntii the last car has passed thereover.

lt is the usual enst-ein, in the operation of switches, to transfer anio-ving train from one track to another, for one of the trairrV tounlock the switchand throw it hy ing to a stop, and to permit theautomatic ciosureafter the train has entered the siding.

in the drawings iorming part of this ap` plication,-Figure 1 is a planView showin the switch in a closed position, that is withthe main lineopen. Fig.' 2 is a View similar to Fig. l with the switch opened and themain line closed. Fig. 3 is a side elevation showing the relativearrangement ot' the projection on al'portion of theengine and thedepressible bar operable therefrom. and by which the switch is operated.'Fig. 4 is a' detail Vlew in elevation, partly in section, onv

Fig. 5 is a detail View` in elevation,partly in section on the line 5-5, Fig. 2, which shows the position ofthe parts with the f car-wheel in place on the second bar that holds theswitch open. Fig. (i is a transverse sectional View on the line 6--6,Fig. l, illustrating the position of the operative parts in theirnorin-ai position with the switch closed. Fig. 7

tive devices placed between the rails and sln'i'wing the' switch closed.Fig. 9 is a View similar to Fig. 8 showing-the switch opened. Fig. i0 isan enlarged View oit' the operative part' within the casing. Fig.- ll isa transverse, sectional View on the line ll-ll, Fig. l0.' Fig. l2 is anenlarged detail View showing the operating lever, the form of slottherein, and the position the pin occupies in the slot both in the openand closed position of the switch points.

Referring to the drawings, @designates the rails oi the main track orline; L and c the movable point or tongue members of the switch rails/;c an operating lever having an angular-shaped slot f in the inner endthereof for receiving the pin f/.which extends upward' from the rod zthat con in a closed position. `With the pin in this position it isacting toward or against the pin j. The' right-hand-end of the slot isformedl on an arc of a circle, the center of which is the pivot-pin j.Then the `projection lwon the engine engages the bar o and moves -theyhar lc downward flush 'wilh the upper surface of the rails (seeFig.',7) the lever c is operated about its pivotI y', and during thefirst portion of the movement or travel, the pin gf 'will remainstationary and also the bar l1, because the right-hand end vthe positionof the parts when the oi' the slot. is 'formed on an are oit a circlewhose center 1s the pin y. During the latv ter part of the lmovement ofthe levere, the

pin g and bark are'moved so as to move the points Z) and c into theposition shown in Fig. 2, that is With the main line closed and theswitch open. As the inner end of the lever e travels from the positionshown in 1 to that shown in Fig. 2it is clear that the pin g and bar hwill be moved and the switch' points opened. The left-hand end of th'slot f extends practically parallel with the sides of the lever f andintersects or leads into the right-hand end of the slot which is formedon the are of a circle ing z' at the point y' and is attached to theAdeprcssible bar ll: by means of the link m', the outer end ot'the levere being attached to the bar by neans of the flexible connection Abell-crank lever s is interposed between the connection 7 and the bar 0and pivoted to the casing s1 at s2.

5* designatesa link `wl' 'ch supports the opposite end of the bar in a'parallel ruler manner. v

.1f designates the spring' which is attached to the operating lever@ anda fixed part of the casing z'. rthis spring serves to hold the bar 0elevatedl as shown in Figs. 3, 4, and 6. The bar 0 is placed in thecasing member s1 with its upper ,surface normally projecting above theupper edge 'v a slight distance.

The link m causes the bars o and /f to inove together: because when thebar 0 is struclcby the projection il; on the engine this bar isdepressed which causes its inotion to transmitted to the lever e bymeans of the connection 1'. rThe link m is also attached to the lever e,and the bar Theret'orewhen the bar o is depressed the bar L will besimultaneously moved downward. Therefore, when the projection fw on theengine, (which is shown at the left of Fig. 3,) strikes the bar o. thebur /u 'falls 'downward and forward into the position shown in Fig. 7,(that is it falls from the elevated position shown in Fig. 6 to theflush position shown in Fie'. Tl), the wheel o the engine, shown indotted lines in Fig. 7, holding the bar /r downward, thus openinc' theswitch Joints` as shown im Fic. 2.'

The pin g, meanwhile, has traveled trom its positionshown 1n Flg. 1 tothe opposite end @oserei projection w has left the bar'p, the weight. oft-hetrain Serves to hold the switch open, and the passing of the lastcar-Wheel from the rear end of the train permits its. en

werd return to the closed position shown in Fig. 1.' The bar lo that isattached to lever c is provided with notches ai and y, and these notchesadord shoulder por tions e which rest on projections 3 and Lt..

These notches and shoulder portions permit the bar 7c to move backwardand forward and up and down;- i

Referring to thev modiiioations shown in Figs. 8, 9, and 11: 5designates e. ons which is located between the rails of 'the track andwhich serves to cont .n the operative parte for moving the sw; in this"Cill.. respect it diil'ers from the construction just described inwhich the operative parts are located outside of the rails. Referring tothe details oi this modifi cationfwt` indicates a lever. which ispivoted to the 'upper pord tion' of the box 5 and this lever is adaptedto be struck by the projection 7 on the moving train, Attached to thelever 6 is a har 8 that is provided with a pin Si which 'works in a slot10 of the lever 11, the outer end of 'the lever being provided with en.outwardly.

opening slot or recess 12 which receives a pin on the bar 13, Whichbaris connected to the movablemernbers b and-c.

Thisaction permits the har 8 to move the bar 13 into the open position shownin -Fig. 9. it the saine time the bar 15 falls into a position that isiush with the upper surface of the rails. The

` wheels of the train o't cars now engage the bar as before described.and hold the switch .1 'r v1 points b and c open. Ihe 'spring 19 willreturn the switch to the closed position att-er the train has passedinto the spur-track. During this return niovenient the pin 18 re entersthe slot 12 and the pin 9 moves to` the opposite end ot the slot 10,whereby the switch is held locked again in its closed position, as shownin Fig. 8.

It will be noticed that in 8, 9, and 10 the piece G isprovided with aninclined edge G1 at its lett side, the purpose of which is to throw theswitch pointsb and c into 130 of the slot f, as shown in Fig. 2.
